I have always used a multi meter when fault finding but after looking at various you tubers namely scannerdan i fancy trying a scope, the problem is the cost of a pico 4 channel automotive scope 4425a starter kit £1400 inc is expensive for the occasional use.
I have a couple of classic cars so primary/secondary ignition, battery voltage, charging and starting would be checked, we also have a couple of modern cars to look after.
I have watched you tube videos of the 2405a in use on automotive diagnostics and provided you take necessary precautions (attenuators) regards input voltage being over 20v then they look to give good results.
I am familiar with the difference in safe voltage between the two mentioned above scopes but apart from that would i really struggle to get good consistent results from a 2405a scope for diy automotive diagnostics.
My question is, will the £385 inc 2405a scope be adequate enough for most automotive fault finding on a diy basis bearing in mind the £1000 price difference between the scopes?
The cost of the Automotive scopes is a major factor to consider and I agree that for minimal use, it’s a big “ask” however, there is so much more than cost to consider
I have listed the majority of considerations here viewtopic.php?p=87821#p87821 and these still apply but now we have BNC+ probes, “ease of use” is taken to another level with the 4425A (especially in conjunction with PicoScope 7 here https://oem.picoauto.com/p7beta/download)
To answer your question, you could use the 2405A for your automotive fault finding on a DIY basis but it will come with limitations in terms of essential hardware/software features, resolution, ease of use and future development
